In detail, the invention comprises a comb C Another method of operating the apparatus provided with a cylindrical hollow back I, spaced is to immerse the comb C in a container of fluid, longitudinally on which is provided a plurality operate the motor 5 for a short interval to create of teeth 2 each of which is hollow, in communisuction in the system to draw some of the fluid cation with the interior of the back I, and open into the comb and conduit 3, and then cause dis- 30 to provide a discharge orifice at its distal end. charge of the fluid from the teeth 2 by reversing One end of the back I is closed and the other the motor to create a reversal of flow of the fluid, end projects slightly to provide for the attachthis of course being done after the comb has been ment theretoof one end of a flexible conduit 3, placed in the hair.

It will be seen that said back, each of said teeth being hollow and when the comb is moved through the hair, the provided at its end with an orifice in communi- 55 UNITED S cation with the recess of said back, a flexible hollow conduit secured at one end thereof to said back, the interior of said conduit being in communication with the recess of said back, a hollow casing having a discharge port therein connected with the other end of said conduit with the interiors of said conduit and casing in communication, a fluid-impelling rotor rotatably mounted in said casing, a reversible motor operatively connected with said rotor, a handle carried by said motor, current conducting leads for supplying electric current from a source of current to said motor, and a switch connected with said leads for reversing the current flow therethrough to selectively vary the direction of rotation of said motor.
